FRIEDRICH WVILl-IELM SCHNEIDER, OF TRIBERG, GERMANY.

PASTE-CARRYING MACHINE FOR ELECTRIC ACCUMULATORS.

SPECIFICATION forming part of Letters Patent No. 576,163, dated February2, 1897.

Application filed January 13, 1896. Serial No. 575,296. (No model.)

To ttZZ whom it may concern:

Be it known that I, FRIEDRICH WILHELM SCHNEIDER, a subject of the GrandDuke of Baden, and a resident of Triberg, in the Grand Duchy of Baden,in the Empire of Germany, have invented certain new and useful ImprovedPaste-Oarryin g Plates for Electric Accumulators, of which the followingisa specification.

The present invention consists in improved paste-carrier plates foraccumulator-batteries, and especially those used for the driving ofvehicles or like purposes, which with proportionately little weight canbe charged with an increase of quantity of current of two to threeainperes or more per square centimeter, and which is insensible toefiects of sudden current variation, as the starting of a boat or acarriage which is driven by accumulatorbatteries. These results arecaused by the particular construction of the paste-carrying plates, asshown in two forms in the annexed drawings, which give an extremelyfavorable distribution of the paste for diminishing the internalresistance.

Figure 1 is a front view of such plate with undulating bands therein.Fig. 2 is a longitudinal section of the same. Fig. 3 is a crosssectionalview of the same. Fig. 4 is a front view of a modification of the platewith bands of zigzag form therein. Fig. 5 is a longitudinal sectionthereof. Fig. 6isacross-sect-ional view of Fig. 4.

The plate is composed of a frame a in the form of a grate, the bars I)of which are united by undulating bands, Figs. 1 to 3, or bands ofzigzag form, Figs. 4 to 6.

Into the hollows formed by the bars I) and the bands 0 the paste is put.The projections f of the bars b prevent the falling out of the paste.

To provide for thein troduction of the counter form or mold necessary toform the projections f when casting the plate, the bands care providedwith corresponding openings e. To hold the paste on the exterior facesof the undulating bands cor those of zigzag form (in the formsrepresented in Figs. 4 to 6) and to prevent the scaling off of the pasteat those places, the bands 0 are provided with vertical projections 61.

Accumulator-batteries made up with the paste-holding plates abovedescribed can be charged and discharged in shorter time, and for thisreason and the reduction of the total weight below that ofpreviously-used second ary elements they are especially suitable fordriving vehicles.

' I claim as my invent-ion A paste-carrying plate for electricaccumulators consisting of a frame a and parallel barsb therein havinglateral projections fand being connected each to the next by bridges cin form of undulating or zigzag bands said bridges having respectivelyon their front and rear sides lateral openings 6 and central projectionsd perpendicular to the faces of the plate substantially as described andillustrated.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

FRIEDRICH WILHELM SCHNEIDER.
